SPECIFICATION forming part of Letters Patent No. 625,375, dated May 23,1899.

Application filed June 1, 1898. Serial No. 682,292. (No model.) I

To aZZ whom it may concern:

Be it known that I, J OHN WINSOR, a citizen of the United States,residing at Corry, in the county of Erie, State of Pennsylvania, haveinvented certain new and useful Improvements in Type-Writers, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to type-writers, and particularly to theapplication or arrangement of the type-bar brackets in relation to thesupporting-disk carried by the frame of the machine.

The invention has for its object to permit the application of a type-barhaving an extended or long bearing within its supporting bracket in sucha manner that the largest number of said brackets may be applied to thedisk of the machine within a stated area. This object is accomplished bylocating a series of these brackets with their pivotal ends in the samevertical plane and at an equal distance from the axis of thesupporting-disk that is, supporting two of the brackets above the diskand two below, whereby the long pivots may be so nested as to permit theapplication of four type-bars, one beneath another, with their pivots atan equal distance from the axis of the disk.

The invention has for a further object to produce an improvedconstruction of the several parts for permitting this arrangement of thetype-bars, each upon a similar pivotal center, and the free movement ofthe same when so nested or arranged.

Other objects and advantages will hereinafter appear in the followingdescription, and the novel features thereof will be particularly pointedout in the appended claims.

In the drawings, Figure 1 is a detail section illustrating a series offour type-bars in position upon the supporting-disk. Fig. 2 is a similardetail section with the said bars at rest. Fig. 3 is a detail frontelevation of a series of type-bars. Fig. i is a top plan View, and Fig.5 is a detail, of the pivotal end of one series of the type-bars.

Like letters and numerals of reference indicate like parts throughoutthe several figures of the drawings.

The letter A designates a disk or other supporting-surface carried bythe frame of a type-writer, from which the type-bar brackets aresupported. Above this disk the usual platen A is located and carried inthe movement of the carriage across the disk. The disk beneath thisplaten is cut away, as at A so that the platen may be lowered. to bringthe lines of contact between the platen and the type-bars more centralfor heavy or thick manifolding work. It is also proposed to omit severalof the type-bars beneath or at the cut-away portion of the disk, so asto not interfere with the travel of the platen above the disk.

The type-bars are arranged in a series of four bars, each numbered 1, 2,3, and 4, respectively, in their descending order and ofslightly-increasing length. For the purpose of illustration in thisapplication only a portion of the bars have been illustrated; but in themachine when constructed the disk will carry a number of type-barsforinstance, eighty-four in the complete circlethe pivot of each bar beingeleven-sixteenths of .an inch long. These type-bars are supported in twobrackets of diiferent characters. For instance, the brackets B aresimilar in shape and configuration and support the bars 1 and 3, whilethe brackets B are provided with a bearing in a plane lower than thebrackets 13 and support the bars 2 and 4. By reference to Fig. 1, whichis taken upon the line 1 1 of Fig. 3, looking in the direction of thearrow, it will be seen that the bars 1 and 2 are supported by the upperset of brackets B and B, which brackets rest upon the upper face of thedisk and are clamped thereon by means of a screw G and an interposedplate 0. The depending pivot end of the bracket B permits the longbearing of the bar 2' to lie beneath a portion of the bearing of thebar 1. Likewise the second set of brackets B and B, which support thetype-bars 3 and 4, respectively, are located beneath the ring and areclamped against the under face of the same by means of a screw D, whichengages a clamping plate D. This screw D passes through an aperture 0formed in the plate 0 between the screws 0, and is threaded into theplate D. The brackets supporting the type-bars 3 and 4 are nestedsimilarly to the upper set of brackets 13 and B, with the exception thatthey are slightly moved to one side, so that the type-bars will not liebeneath the corresponding bars in the upper set, but will be locatedbetween the same. For instance, as illustrated, the bar 4. will liebetween the bars 1 and 2 and thebar 3 between the bar 1 of one seriesand the bar 2 of the next adjacent series. 7

Each of the brackets B and B is composed of a loop portion 1), by whichthey are clamped in position and at their outer ends are olfset, as atI), immediately adjacent to the long bearings E, carried by thetype-bars. This structure of bracket supportsthe bearing, while theinner end of the type-bar lies between the walls of the loop I), and isthus held against lateral movement. The inner end of each of thetype-bars is pivotally connected with the usual rods F, which areoperatively connected with the keyboard of the machine, as usual. Theseries of typebars when they are at rest bear upon the usual ring Gr,supported by the frame for that purpose, and each of the bars carries atits outer end asuitable type. The type-bars of each series are pivotedin successive planes in a descending order, so that the bar 4: is thelowest of the series. This, it will be understood, is necessary to bringthe type-bar pivots in a vertical line and at an equal distance from theaxis of the ring and to concentrate a number of bearings in a smallarea. The outerend of each of the bars is also suitably offset or bentto throw the bar into its proper alinement, which is necessary in viewof the lowering of the bars in the series. The inner or pivoting end ofthe bars may also be suitably cut away or recessed to preventinterference with adjacentbearingsorbrackets. For instance, the bar 2 iscut away at E upon its under side to prevent contact or interferencewith the pivot of the bar 3, which lies immediately mit the proper swingof the bar without in terference with the pivot E of the bar- 2, whichis immediately above the bar 3. The pivotal ends of the bars 1 and 4 maybe substantially the same, as they are not in such position as tointerfere with the pivots or brackets of adjacent bars. This recessingmaterially assists in permitting the close assemblage or nesting of thebars and their brackets, which is also greatly facilitated by means ofthe offsets in the brackets located immediately adjacent to thepivoting-point for the type-bar. By this means a series of foursuccessivelylowered barsmay be used and all of the pivots located in thesame vertical plane. This location of all of the type-barpivots in thesame vertical plane at an equal distance from the axis of the ring is avery material and essential improvement in this art, as it permits themost advantageous length of pivot to be which is essential to the mostdesirable class of work.

It will be obvious that my improvement can be applied to any class oftype-writers and that the brackets and type-bars may be increased ordiminished in the number of series used and various means for securingthe same applied without departing from the spirit of this invention asdefined by the appended claims.

Having described my invention, what I 1 claim to be new, and desire tosecure by Letters Patent, is
